Activity Links
These links are for activities, designed to illustrate concepts of statistics as presented in class. The Cast site is particularly good to study concepts and review material.
CAST  When you login to this site, your login name is Math123@middlesex.cc.nj.us and your password is 6312. This site, developed in Australia, has a variety of activities for statistics. It also presents statistics with a bit of an accent! There are quite a few interactive graphs to check out. 
Histograms  This activity is to see how the shapes of histograms are affected by changing the class width (called the bin). 
Mean and median  This activity allows you see the effect of changing data values on the mean and the median. 
How fast are you?  You will have fun here! But make sure that the mouse is good! You will generate a set of data and see the descriptive statistics. Are the times the same? 
Guessing correlations  This site allows you to practice guessing the coefficient of correlation for various sets of data. You can see if you can break the record! 
Effect on outliers on Regression  This site allows you to add a data point and see how that affects the regression line. 
Lets Make A Deal  This is a probability site. You get to select a door. Hope there isn’t a donkey behind it. 
Sampling distributions  This is a demo of the Central Limit theorem. 
Confidence intervals for the mean  The name says it all! 
Confidence intervals for proportions  The name says it all, too! 
Approximating the binomial distribution  This shows how the normal curve can be used to approximate the binomial distribution. 
Goodness of fit  This site show how the Chi square goodness of fit test is demonstrated. 
Slope and standard Error  This site shows how the slope of the best fit line and the standard error of estimate are affected by different data points. 
Contingency table  This site demonstrates a 2 by 2 contingency table with the Chi square test. 
Virtual lab  This site has several activities.
